A good and correct understanding of concepts is a fundamental thing that prospective Physics teachers must have before graduated from college. Therefore, it is necessary to identify the conception to ensure that there are no students who have misconceptions and do not understand the concept. This study aims at identifying the misconceptions experienced by prospective Physics teachers at the final level, especially in the friction force material. This is descriptive research conducted in a university in Mataram with 12 students involved. The instrument used was a three-tier test in the form of a multiple-choice test with open reasons. A total of 10 items with 30 questions were used in this study. Data collection techniques used was tests and interviews. The data that has been collected was then analyzed using descriptive statistics. Based on the results of the data analysis, it was found that 46.29% of the students had misconceptions with details of 50.00% of the students experienced misconceptions in determining the type of friction force, 43.75% in determining the direction of friction force, and 47.22% in determining the magnitude of the friction force. The results of this study indicate that there are still many students of prospective Physics teachers have misconceptions. Therefore, we need an alternative learning that can be used to reduce the misconceptions had by prospective Physics teachers.

Phytoplankton is one of the important components in aquatic ecosystems. This organism plays an important role as a primary producer to support the life of the tropics above it. The purposesÃÂ of this study were to reveal the abundance and diversity of phytoplankton species in the waters of Sekotong Bay, West Lombok. Sampling were conducted in July 2018 at 8 stations using plankton net and then observed at the Laboratory. The results of the abundance calculations show a varied pattern at each observation station. The highest abundance was found at station 8 (9,060 ind/L) followed by station 6 (8,300 ind/L), station 7 (6,490 ind/L), station 4 (4,440 ind/L), station 3 (3,980 ind/L) , station 5 (2,820 ind/L), station 2 (2,460 ind/L) and station 1 (2,440 ind/L). The Shannon - Wiener Species diversity Index also shows diverse patterns at each station. Station 7 has the highest diversity index value (HÃ¢â¬Â² = 3.55), followed by station 6 (HÃ¢â¬Â² = 3.46), station 8 (HÃ¢â¬Â² = 3.18), station 1 (HÃ¢â¬Â² = 2.72) , station 2 (HÃ¢â¬Â² = 2.69), station 5 (HÃ¢â¬Â² = 2.67), station 4 (HÃ¢â¬Â² = 2.33) and station 3 (HÃ¢â¬Â² = 2.26). Species dominance index at all stations at low category with the highest dominance found at station 3 (D = 0.19), followed by station 4 (D = 0.18), station 2 (D = 0.09), station 5 (D = 0, 09), station 1 (D = 0.08), station 8 (D = 0.06), station 6 (D = 0.05) and station 7 (D = 0.04). Species Evennes index (E) values ranged from 0.71 to 0.88, indicating that the number of individual species wasÃÂ relatively the same and the ecosystem was in relatively good condition. The analysis showedÃÂ that the spatial pattern of abundance and diversity of phytoplankton species in Sekotong Bay was related to the distance from the estuary.

Anti-inflammatory medications are necessary to treat excessive inflammation reactions due to injury, infection, or irritation. The emergence of several adverse effects associated with synthetic anti-inflammatory drugs has prompted the continued use of anti-inflammatory agents derived from natural products with low side effects and a high therapeutic effect. While it is well established that the seeds of the Makassar fruit (Brucea javanica (L.) Merr.) ÃÂ have anti-inflammatory activity, the optimal concentration of Makasar fruit seed extract for anti-inflammatory activity is unknown. This study aims to determine the optimal Makassar fruit seed extract concentration as an in vitro anti-inflammatory. The seeds of the Makasar fruit were extracted using the sonication method (3 x 35 minutes) in 96% ethanol and then concentrated using a rotary evaporator. The secondary metabolites of Makasar fruit seed extract were then identified in the test tubes, and the anti-inflammatory activity was determined using the protein denaturation inhibition method. The results indicated that the extract produced had a yield of 10.03%. The Makassar fruit seed extract contains secondary metabolites of phenolics, flavonoids, and terpenoids. Makasar fruit seed extract exhibited the optimum anti-inflammatory activity at a concentration of 1%, with a 55.47%ÃÂ inhibition of protein denaturation.

The Kawasan Rumah Pangan Lestari (KRPL) or Sustainable Food House Area integrated with Trigona sp. bee cultivation can be an alternative livelihood to improve the community's economy. This study aims at analyzing the development of bee colonies in KRPL in terms of the number of pollen pots and honey pots produced. The type of this research is descriptive qualitative. The study was conducted from October to November 2020. The samples used were 14 colonies, categorized as strong colonies, medium colonies and weak colonies. The increase in the number of empty pots, honey pots and pollen pots were observed every three days. Environmental factors such as temperature, humidity and light intensity, and the activity of the Trigona bees were also observed. The results showed that the average temperature at KRPL was 29.80 ÃÂ°C, with an average humidity of 69.62% and a light intensity of 22610 lux. Most of the increase in the highest total number of pots occurred in strong colonies. The number of empty pots, honey pots and pollen pots increased on different days. In the last week of the observation, most of the colonies did not increase in the number of pots. Development of Trigona sp. bee colonies in KRPL is considered slow even though the environmental conditions there are normal. Cultivation of Trigona sp. in KRPL should use strong colonies rather than medium and weak colonies.
